the distilling flask because of their high boiling points. However‚ since a small amount of water may still appear after transferring the product from the conical flask‚ a drying agent is used to separate the cyclohexene and the remaining water is removed. Cyclohexene is insoluble in water and thus is not lost using a drying agent. Experimental The procedure began with weighing 10.0460g of cyclohexanol which was put directly into a 100ml round bottom flask with a cork ring. Then‚ 3ml of 85%
